Mainly Google Now. I like how it keeps track of my shipments, the restaurants in my area and Google Maps is pretty much unrivaled. Hell even Apple had to bow down.
Well I use a variety of apps for that. For shipment tracking use and excellent app called Package Tracker. Its compatible with all international mailing services and does a great job for me. You do have to enter the tracking numbers for it to get started though, which for me isn't a big deal.
As far as restaurants, between yelp and bing, i have great access to restaurants and good reviews. I don't trust google maps because they allow business to buy advertising that can falsely push places to the top of your results. I've found yelp to be alot better in giving accurate representation of the local favorites.
And as far as mapping goes, Nokia Maps takes a VIOLENT shyt on google maps that its not even fair. Primarily because its not CONSTANTLY TRACKING YOUR EVERY MOVE, and its maps are DOWNLOADABLE. This past May i was in France for two weeks. I was able to dowload all the maps for France into my phone for accurate offline GPS without the need for internet. This is fukking huge. Every nokia phone is essentially an offline GPS device as well. This advantage alone makes it far superior to Google offerings, even if they are very good otherwise.
Just my 2 cents though.
